Well when i bought my car i didnt realy know a great deal about the rst's. I was looking for a long term project that i could learn loads of stuff off as i went along. An rs seemed to be the logical way to go and iv never looked back from then on. Iv turned from liking them to an absulute loving them with a passion!
When you buy your first rs you probably dont know a great deal about them but i can garantee by the end of it you become a master mechanic or very poor person lol.
